    What happens to my 4 Ohm speaker if I use it with an 8 Ohm amp? Can I damage something?

    the current asked by the speaker will be to high !
    if you have a 8 ohm speaker or higher then there is no problem . If you still want to use this speaker
    connect a same one serial then you'll get

    4 + 4 = 8
     
  4. Do you mean that your amp is not meant to be run at less than an 8 ohm load? That would be very unusual for a modern bass amp. Most have 4 or 2 ohm power ratings. What amp do you have?

    To underscore what Basswou said, if the amp has a minimum impedance rating of 8 ohms and you run a cab from it that is rated at 4 ohms, the amp will overheat and fry itself.

    His serial method will definitely work fine, but you're better off using cabinets that are propely matched to the amp.
